▎ 摘　　要

In this study, graphene oxide (GO) was used to modify the polypropylene fiber filter membrane. The GO modified polypropylene fiber filter membrane (GO-PP fiber filter membrane) was obtained using vacuum filtration. The performance of the GO-PP fiber filter membrane was tested to filter the practical water-based paint wastewater. GO-PP fiber filter membrane has better treatment effect and stronger anti-pollution performance than commercial PP fiber filter membrane. Chemical oxygen demand (COD), membrane flux and suspended solids (SS) were used as indicators to characterize the performance of the GO-PP fiber filter membrane. The combination process of flocculation and PP fiber filter membrane for wastewater treatment was studied. The optimal COD and SS removal rates were obtained using flocculation + GO-PP fiber filter membrane unit as 84.8% and 84.6%, respectively. These results suggest that the GO-PP fiber filter membrane could be a potential material for water-based paint wastewater treatment.
